FIFA prosecutor: Probe already had Qatar evidence

Garcia said his report would be "comprehensive and fair to all parties."

Since last October, Garcia and his team have interviewed officials from the nine bid candidates, and reviewing evidence from whistleblowers.

Qatari officials were the last to be visited, in Oman 24 hours after the first round of Sunday Times allegations.

Garcia delegated his Swiss deputy, Cornel Borbely, to quiz officials from his home country and Russia. There, Garcia is barred from entry for his previous work prosecuting a Russian arms dealer.

Garcia said he also spoke, or attempted to speak, with all members of the FIFA executive committee from 2010. Several have since resigned or been suspended while under investigation for financial wrongdoing.

After Garcia arrived in Zurich to meet with current board members in March, some reportedly agitated to remove the American from his post.
